Transmission fluid, like in automatic transmissions of cars, is used to transfer the power of the engine to the drive shaft. It's a hydraulic fluid, and the transmission is a hydraulic pump and a hydraulic drive all in one. The motor drives the pump (the torque converter), and it compresses the transmission fluid which in turn drives the clutch assembly.
The same as it mean everywhere else - that depressing the clutch pedal pressurizes a hydrualic fluid, and that pressure is then used to operate the actual clutch mechanism in the transmission.
